Error opening URL "file:///C|/flashplayer/undefined"

[spectator]

I am trying to write a simple flash mp3 player. I am using XML and in it I have
<Playlist>
<Song URL="track1.mp3">Singer1</Song>
<Song URL="track2.mp3">Singer2</Song>
<Song URL="track3.mp3">Singer3</Song>
<Song URL="track4.mp3">Singer4</Song>
</Playlist>

I have a list with the songs which appears and when you choose one of the songs and release play_btn you should hear it, but it gives me this error

Error opening URL "file:///C|/flashplayer/undefined"

What does this error means? Is it my xml file fine ?

P.S. Please help. I am a newbie :)

Do you have some code to show? You are probably not accessing the XML nodes and/or attributes correctly.
